Drill-Driven Copper Tube Expander Alloy

A purpose-built electric tube expander for HVAC technicians performing air conditioner and refrigeration system work. Built from robust alloy steel for long-term resilience against impact, vibration, and torsional stress encountered during field service. Its compact form factor allows one-handed operation and easy transport between jobs. Designed to interface seamlessly with common cordless or corded hand drills—eliminating the need for manual cranking while maintaining full control over expansion depth and speed. Optimised for expanding annealed copper pipes used in R32, R410A, and R290 systems—supporting compliance with UK F-Gas regulations through reliable, non-destructive tube preparation.
